某矿用循环硝酸法从贫锰矿粉中制取电池工业用的优质活化锰粉的中间试验结果证明,利用含锰26％的贫锰矿粉能够制取含锰55％、放电时间平均在1100分钟以上的活化锰粉。这种锰粉经电池厂做成电池放光试验证明,在放电过程中高压(0.9伏)部时间达360分钟以上,比天然锰粉好。是一种比较理想的电池原料。试验制取这种锰粉的工艺流程主要包括三个部分。 (一)原料准备:试验所用的贫锰矿粉,为硬锰矿和褐
The results of an intermediate test of producing high quality activated manganese powder for battery industry from lean manganese ore powder by a circulating nitric acid mine method show that manganese can be prepared by using lean manganese ore powder containing 26% manganese and the discharge time is on the average of 1100 minutes The above activated manganese powder. This manganese powder batteries made by the battery factory beam test proved that during discharge high voltage (0.9 V) Department of the Department of more than 360 minutes, better than natural manganese. Is an ideal battery material. Experimental production of this manganese powder process mainly consists of three parts. (A) Preparation of raw materials: The lean manganese ore used in the test is hard manganese ore and brown
